Files that were changed since the 8-10-95 release.  

DISCWIN.EXE

HCC.EXE

WINGAUGE.EXE

WINGUARD.DRV

This release was made in order to support foreign versions of Windows 3.1x.

11-10-95 1.02 release

Hurricane 1.02 provides full support for international
versions of Windows including Arabic, French, German,
Hebrew, and Japanese.

Combo boxes - The Heap Expander now provides enhanced
support for a variety of combo boxes.  The new HURRICAN.INI
section, [HeapxCompatibility], allows users to dynamically
add special Heap Expander support to applications with
misbehaved combo boxes under Hurricane.  See "New INI
settings" below for more details.

HP Printers - Enhancements has been added to the print cache
to support HP printers using  HP's Printing System For
Windows.  To enable this support perform the following
steps:

1.  Edit the HURRICAN.INI and add on a separate line
    "IgnoreSpoolerFlag=True" in the [PrintCache]
    section. (do not include the quotes)
2.  Run Control Panel | Printers and uncheck the
    "Use Print Manager" selection box.

AVI - Enhancements to the Heap Expander allows viewing
of AVI files without having to lower the User Threshold
settings first.

AUTOCAD 13 - Add the line "HeapOptimizer=OFF" under the
[Vcache] section in SYSTEM.INI to circumvent a Win32s
anomaly.

Transparent Language - The audio portion of this program
fails when the Heap Expander is on.  While testing this
program with Hurricane, our engineers found that the
problem is with Transparent Language's method of heap
allocation.  In fact, the reported problem occurs
without Hurricane when Transparent Language is executed
after several programs have been loaded into memory.
The setting "TLP=TLPStory" in the [HeapxCompatibility]
section of HURRICAN.INI will supress Transparent Langauge's
problem while Hurricane's Heap Expander is running.

SuperVoice - Enhancements to the print cache allows
print caching while SuperVoice is running.

New INI Settings:

A [HeapxCompatibility] section is provided to allow support
for a variety of combo boxes.  A combo box is an edit box
with a button that provides a list of predefined
selections.  The format for this section is as follows:

ApplicationName = ClassName

Where ApplicationName is the name of the application and
ClassName is the name of a Windows class that the
application is using to display the combo box.  The Heap
Expander has been enhanced to provide both values and update
the HURRICAN.INI automatically.  If you have an application
that exhibits any problems displaying combo boxes, follow
this procdure:

1.  Edit the HURRICAN.INI and add on a separate line
    "SetParentAssist=True" in the [HeapExpander] section.

    [HeapExpander]
    SetParentAssist=True

2.  Restart Windows and use the combo box as before.  A
    dialog box should pop up to inform you on what to do
    to maintain compatibility between the Heap Expander
    and your application.
3.  Edit the HURRICAN.INI and remove the
    "SetParentAssist=TRUE" statement from the [HeapExpander]
    section and restart Windows.

The new "AllocPageFixed=True" setting under the [Vcache]
section in SYSTEM.INI provides enhanced support for Windows
configurations that use temporary swap files.  If you are
using a temporary swapfile with Hurricane's Virtual Cache,
edit the SYSTEM.INI and add on a separate line
"AllocPageFixed=True" under the [Vcache] section.

The new "LDTProtection=OFF" setting under the
[Heap Expander] section in HURRICAN.INI will disable the
Heap Expander's LDT protection.  This is necessary for
the Heap Expander to avoid problems with programs that do
not allocate Local Descriptors properly.  The symptom is
usually an "Out of LDTs" warning from Hurricane when
you try to execute a program.  The only program that we
found that exhibits this behavior is IBM's Antivirus 2.2.
If you are using this program, edit the HURRICAN.INI and
add the line "LDTProtection=OFF" under the
[Heap Expander] section in HURRICAN.INI.
